 WireGuard is a relatively new but very important technology which was recently added to the Linux kernel. WireGuard creates very fast but simple encrypted tunnels between devices. From the `WireGuard <https://www.wireguard.com/>`_ website, "it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry."
 
-Previous solutions like OpenVPN and IPSec are considerably more heavy and complex, while being less performant. All existing VPN tunnelling solutions will cause a significant increase in your network latency. WireGuard is the first to achieve near over-the-line network speeds, meaning you see no signigifant performance impact.  With the release of WireGuard, there is little reason to use any other existing tunnel encryption technology.

-A machine in a Netmaker network, which is managed by the Netclient, is referred to as a Node, as you will see in the UI. A Node can be a VM, a bare metal server, a desktop computer, an IoT device, or any other number of internet-connected machines on which the netclient is installed. A node is simply an endpoint in the network, which can send traffic to all the other nodes, and recieve traffic from all of the other nodes.

 15. Netclient configures WireGuard with this information. At this point, the node is fully configured as a part of the network and should be able to reach the other nodes via private address.
